Patent number: 7677739Abstract: A projector includes a lens cover which is slidable relative to a chassis for covering and exposing a projection aperture of a projection lens. A detecting section includes a light emitting portion which projects a light beam and detects the opened state or closed state of the lens cover depending on the absence or presence of the light beam received by a light receiving portion. The light emitting portion and light receiving portion are disposed so that the optical path of the light beam projected from the light emitting portion and received by the light receiving portion intersects the slide direction of the lens cover. A light shielding portion is provided in the lens cover. The light shielding portion is formed in a predetermined width in the slide direction of the lens cover.Type: GrantFiled: February 21, 2007Date of Patent: March 16, 2010Assignee: Seiko Epson CorporationInventor: Akitoshi Kuroda

Patent number: 7204598Abstract: According to exemplary embodiments of the present invention, in a projections lens position adjuster, when a part of a dial exposed from an exterior case is rotated downward, a gear is rotated in an R2 direction. A Y-slider is then moved downward (in a Y3 direction). Accordingly, a Y-table is moved downward, as is a projection lens. When the part of the dial exposed from the exterior case is rotated upward, the projection lens is moved upward. When a part of a dial exposed from the exterior case is rotated leftward. In contrast, when the dial is rotated rightward, the projection lens is moved rightward. Provided around the projection lens are a first light shield for closing a gap between an opening of a front case and a periphery of the projection lens, and a second light shield for closing a gap between the projection lens and a hole of a base of the projection lens position adjuster.Type: GrantFiled: June 26, 2006Date of Patent: April 17, 2007Assignee: Seiko Epson CorporationInventors: Akitoshi Kuroda, Akira Momose

Patent number: 7014321Abstract: The invention provides a projector that can have a light source device, an optical device that modulates, in accordance with image information, beams emitted from the light source device to form an optical image, and an external case that accommodates the light source device and the optical device. The projector can enlarge and project the optical image formed by the optical device. The projector can include leg portions that are disposed so as to be extendable from and retractable to an outer peripheral surface of the external case to adjust the projection position of the enlarged and projected optical image, an intake opening formed in the surface of the external case disposed with the leg portions, and an intake fan that is disposed inside the external case near the intake opening and introduces cooling air from the outside of the external case. An intake surface of the intake fan can be disposed at an inclination with respect to the plane of the external case in which the intake opening is formed.Type: GrantFiled: October 20, 2003Date of Patent: March 21, 2006Assignee: Seiko Epson CorporationInventor: Akitoshi Kuroda
